In this new chapter in the Oz legacy, Dorothy returns to Kansas only to find it devastated by the tornado that had whisked her away to Oz. The townspeople are packing up and moving out. But shortly after arriving, she is magically transported back to Oz. She finds out that Oz is in trouble and the people there need her help. As she journeys to find her friends, she encounters a number of new companions (and lots of problems in both worlds that she needs to fix).
